Title: Process and device for the electro-optical measurement of distance
Inventor: GACHTER BERNHARD
IPC: G01S17/10
Filed: 1995-09-21
Granted: 2007-01-16
Abstract: A process and device are proposed for the electro-optical measurement of distance based on the pulse delay method.      A number of individual light signal pulses are emitted at predetermined and differing intervals, so that after a number of measurement intervals which determine the measurement zone have elapsed, a pulse sequence is detected. Using mathematical estimation methods, the temporal position of the detected pulse sequence in relation to a reference pulse sequence can be determined and used to determine the delay tim~ By emitting individual pulses at long intervals and high peak power and subsequently combining them to form a pulse sequence, the accuracy of the distance measurement process is significantly improved.

Title: Algebraic codebook with signal-selected pulse amplitudes forfast coding of speech
Inventor: LAFLAMME CLAUDE
IPC: G10L19/125

Granted: 2001-08-21
Abstract: A codebook is searched in view of encoding a sound signal. This codebook consists of a set of pulse amplitude/position combinations each defining L different positions and comprising both zero-amplitude pulses and non-zero- amplitude pulses assigned to respective positions p = 1, 2, ...L of the combination, wherein each non-zero-amplitude pulse assumes at least one of q  possible amplitudes. To reduce the search complexity, a subset of pulse amplitude/position combinations from the codebook is pre-selected in relatio n to the sound signal, and only this subset of combinations is searched. The p re- selection of the subset of combinations consists of pre-establishing, in relation to the sound signal, a function Sp between the respective positions  p = 1, 2, ...L and the q possible amplitudes, the search being limited to the combinations of the codebook having non-zero-amplitude pulses which respect the pre-established function. The function can be pre-established by pre- assigning one of the q possible amplitudes to each position p, the pre- established function being respected when the non-zero-amplitude pulses of a  combination each have an amplitude equal to the amplitude Sp pre-assigned to  the position p of that pulse.

Granted: 2002-03-05
Abstract: An improved messaging system for transmitting message information to a plurality of recipients comprises the steps of: sending a first message including the predetermined message information to a first recipient address of a first recipient on a list of recipients; updating, after the completion of the step of sending, the list of recipients to create an updated recipient list, the updating being implemented independently of the first recipient at the first recipient address; and sending a second message, including the predetermined message information to an address corresponding to a next recipient selected from the updated recipient list. The method can iteratively repeat the steps of updating and sending the message to thereby transmit messages to a plurality of recipients with the list of recipients being dynamically updated after each message is sent. The recipients may have an opportunity to modify or add to the message before the message is sent on to the next recipient.

Title: Method and apparatus for bandwidth reuse in a communication network
Inventor: LU XIAOLIN
IPC: H04J1/08
Filed: 1997-10-10
Granted: 2001-01-02
Abstract: A method and apparatus is provided within a system having a total bandwidth divided into multiple segments. The segments are preferably frequency segments in a frequency division multiplexing environment or time slot segments in a time division multiplexing environment. The system transmits first downstream information from a head end to a router within a first bandwidth segment and transmits second downstream information from the head end to the router within a second bandwidth segment. The router sends the first downstream information to a first destination and sends the second downstream information to a second destination. First upstream information is transmitted from the first destination and through the router to the head end within a bandwidth segment used for downstream transmission other than the first bandwidth segment. Second upstream information is transmitted from the second destination and through the router to the head end within a bandwidth segment used for downstream transmission other than the second bandwidth segment. Upstream information from a given destination is always sent over a different bandwidth from the bandwidth over which the downstream information was received. Further, the router directs respective downstream information to respective EUs while blocking other information to maintain privacy of information.

Abstract: Disclosed are methods useful for treating vascular lesions wherein a non- particulate agent such as a metal coil is introduced into a vascular site (e.g., an aneurysm cavity) in conjunction with an embolizing composition comprising a biocompatible polymer and a biocompatible solvent. The biocompatible solvent is miscible or soluble in blood and also solubilizes the polymer during delivery. The biocompatible polymer is selected to be soluble in the biocompatible solvent but insoluble in blood. Upon contact with the blood, the biocompatible solvent dissipates from the embolic composition whereupon the biocompatible polymer precipitates. Precipitation of the polymer in the presence of the non-particulate agent permits the agent to ac t as a structural lattice for the growing polymer precipitate. In another embodiment, the biocompatible polymer composition can be replaced wi th a biocompatible prepolymer composition containing a biocompatible prepolymer.

Abstract: A system for reviewing files which permits comments to be inserted in files to be viewed with a hypertext browser. When the hypertext mark-up language employed is HTML, text files are converted to an HTML representation. An HTML file is represented by a linked list of objects. Comment insertion markers and comment display objects are inserted at predefined points in the HTML linked list representation. The linked list is stored as a binary file and has a comment file associated with it. Access to the HTML file by reviewers and authors causes the regeneration of the HTML document by a Common Gateway Interface which recreates the linked list representation of the document from the binary file and which then generates HTML code from the linked list. Comments may be entered by reviewers working in parallel on the HTML document.  Comments are displayed at the next regeneration of the HTML document by the system.
